The riddling grate for the Olymberyl Olive is a cast iron centre grate that sits within the grate frame and supports the fuel bed. As solid fuel burns, the riddling action allows ash to drop through into the ash pan while keeping unburnt fuel in the fire. If your existing grate is warped, cracked, or broken, this replacement restores proper ash clearance and airflow. ✅ Compatible with: Olymberyl Olive 🔧 Specifications Weight: 1.51 kg Material: Cast iron Heat resistance: 650°C Part type: Riddling grate / inner circular grate The riddling grate controls how ash moves out of the fire bed. A damaged grate causes ash to build up, restricting airflow and reducing combustion efficiency. Fitting a new one is a straightforward repair that immediately improves burn quality and keeps the stove running cleanly.
